Titan ZG Engine

Titan ZG 45SL

The Titan ZG 45SL combines all the advantages of our ZG 62SL into a compact, low vibration powerplant for your medium size model.

The popularity of the ZG 62 has remained constant over the years. No other model aircraft petrol-engine has come anywhere near the sales volume of this superb engine. Many modellers do not want such large models, but they wish to have a slightly smaller engine with the same reliable qualities of the ZG 62.

For aerobatic models of about 2 m span, many scale and fun fly models, the ZG 45 is the answer. It has not only the outward appearances of the ZG 62.

  • The ignition, flywheel and propeller hub is identical.
  • The crankshaft is also 15 mm diameter which is for this size of engine very robust.
  • Exhaust and inlet is angled to stroke for optimum gas flow.
  • The very light aluminium crankcase was specially developed for us by Zenoah. The ZG 45SL is 200 g lighter in weight than the ZG 62SL and has markedly smaller dimensions.
  • Due to the smaller and of course lighter piston coupled to the same size flywheel makes for a proportionally smoother running engine.

Recommended propellers

The Super Silence Carbon Propellers used for aerobatic models have proved to be especially quiet and at the same time having a very efficient performance. Using our stainless steel silencers the 19×11″, 20×10″, 20×11″ 20×12″ Super Silence Carbon three blade propeller and the 21×12″or 22×10″ two blader are best. With a tuned pipe use the 20×12″ three blade or the 22×12″ Super Silence Carbon two blade prop.

Very suitable but not so quiet is the 20×10″ Menz S wood propeller. Our Piper flies very well with a 20×10″ or a 21×10″ Menz S. But for maximum thrust a 21×8″ Menz S is perfect.

To achieve the quietest possible noise level in flight and at the same time high power, use our Hydro- Mount-System, the stainless silencer, intake air drawn from the fuselage and a Super Silence Carbon Propeller that limits the rpm to 6400 – 7000.

Power- and Torque Curves of the Titan ZG 45SL

These charts were produced from tests carried out by Dietrich Altenkirch for the magazine "model" in 1994. These curves show that the ZG 45SL’s power, when fitted with a tuned pipe, exceeds the power of a ZG 62S fitted with the standard silencer.
